I'm using chart helper on an mvc project but the line chart looks weird or doesn't looks like i want. I've been searching about this subject and the only thing I can find its the charttheme but only one example with series. I'm including this, which is the only example i found about series on chart theme.
Series Name="Default" Template="All" BorderWidth="3" IsValueShownAsLabel="True"
I want to put this dot on the values instead of the numbers. I think the solution must be on "series" because the chart helper doesn't has many options but I can't find what other properties this series has. I have 2 images to upload but I can't because I need more reputation, I will try to update this if I get the reputation needed.

I need to get the opened indicators values (a bunch of this) from a current chart of MetaTrader 4 (by using mql4), and export this values on python (by using ZeroMQ library), in order to create a dictionary of this values and using it for other purpose. I just do that for candlestick data, but that's quite simple. I know there's ChartIndicatorTotal to know number of total indicators on the chart, and ChartIndicatorName to know the names of the indicators on the chart, but I don't know how I should use this functions in order to get the values I want.
when I use the data below in a google sheets timeline chart it doesn't plot 29/04/2019 5% and 10% leaving a gap in a chart, how can I resolve this? the chart should be unaffected by empty fields.

I have tried adding another dataset and I get the error
each values column may be followed by one or two annotation columns. column number 4 is of type date
Here is a link to the spreadsheet
There are gaps in your data, so you're going to have gaps in your chart. That's just how Timeline Chart works. There are ways of having charts skip gaps, but you have the 29th as a date, so it is explicitly part of your timeline.
The least burdensome remedy is usually to chart a different dataset living elsewhere, filtered down live from your input values, but meeting your charting requirements. E.g. elsewhere in your file have it list only the rows where 5% Target is populated with something like =FILTER(B2:E,LEN(C2:C)) and then chart that.
If that's not what you really want, then you need to decide what you really want. A time-cropped chart to only include fully-populated date ranges? A chart with made-up values extrapolated from surrounding data? Those and some other options are not trivial, so you'll need to really determine your requirements and look into how they can be achieved.
I have an MVC application which displays reports based on the report viewer.
Currently, the report has 4 columns and the requirement is to show columns based on the parameters selected.
I had achieved the solution by using sending parameters to the rdlc file and hiding the columns.
But now the problem which I am having is, when the report is exported as excel the last hidden column is showing as an empty column and this is an issue when printing the report from excel.
I would like to know if there is anything that can be done through code so that the column is not generated at all instead of hiding it. had done a lot of research but didnt find any solution. Can anyone please help me... Thanks!!!
One option would be to update the column's cell expressions to not return anything unless the parameter is set to show that column:
=iif(Parameters!HideColumnValue,Nothing,Fields.YourFieldName.Value)
If your column has background or line formatting that needs to not show when the column his hidden, you can set that as well:
Background Color:
=iif(Parameters!HideColumnValue,"White","Gainsboro")
Lines:
=iif(Parameters!HideColumnValue,"None","Solid")
I'm trying to generate a stacked column chart. What I want is similar to this JSfiddle example. However, I have around 30 categories and 1000 series. The series are rather sparse. There are only about 200 values. But because highcharts needs each series to have values across the x-axis categories, I'm forced to submit 1000 series each having 30 values (mostly zeroes). The chart takes over a minute to render. How can I improve this performance?
There is another way you can pass the data to highcharts, where you specify x and y for each point. This means you can skip the 0 values. In the fiddle you quoted, I modified one line to be:
data: [{x:1,y:5}, {x:3,y:7}],
http://jsfiddle.net/rh9aK/
I expect that 1000 series and 30 categories may still be too much, but this is worth a try.
One other thing, have you made sure that you don't have any series which only contain zeros ? If so, you may as well remove them before rendering.
JS charts, in you case, will produce too many DOM elements. It will be too complex for browser. You need some server-side solution which generate graps inside image.
I am quite new to Rails, and I need to work on a report generating plugin using Rails and Highcharts for the output. My main issue is that my user is meant to be able to define a time range using a jQuery datepicker. How can I get the highcharts graph on the x axis to reflect the time range based on the users selection, and how do I tie it to the other fields in the rails model.
Eg. If I have a table with a created_by field which the user is supposed to pick his to and from dates from... and the table also has user_id and the users select a specific language for each application. I want the graph to show for each day the count of the different languages different users selected during their application.
Hope my question is clear enough. Thanks
